After logging into Lawson, if you see the below error “Cannot retrieve user file. Bookmark IDs cannot be read”, there is a good chance that the iosconfig.xml file has some invalid values. The error messages might point you directly to this file. It can be found at LAWDIR/system. Make sure that the ioswebrootdir attribute points to the correct location. This location should be LAWDIR/persistdata. Make sure there are no extra spaces or directory names in this value.
After updating the value, reboot the server or restart the WebSphere services.
